Z 4 o a as -Q if a? o which the coils are mounted provided with covers 38 which in instance are screwed into the tops of the cups, Elolenoid cores, one of which 1s shown st 19 are adepted to move into and out of the coils through the cup covers to operate the switches, as will best. leined leter. Each core is connested at its upper end to s flexible chain or cebleZ'l which is connected to the upper end of the shorter erm of s, Welling-beam lever 21. These walking-below. levers ere rigidly connected to the short, horizontal shafts 22, mounted to revolve or oscillate in the up Wsrdly extending bearings 23. These short shafts ere preferably joined together by the flan ed connecting rod 22 thereby forming s sin is, long elicit, so that both beams will rec. in unison; These Walkingbesins have forwardly extending arms, longer than the reerivordly extending arms previously described. The two lever arms of each beam have enlarged outer feces which are arcs of circles concentric with the pivotal center of the beam.

Attached to the top of each longer lever arm is a second flexible chain or cable 24, which extends downward and is connected in any suitable manner to the vertically movable plunger 14 previously described. Each lever arm is grooved to receive the chain, as is clearly shown. The lever arms are of such lengths that vertical tsngent's to the arcs of the longer arms always coincide with the longitudinal axes of the plungers 14 and the vertical tangents oi the arcs of the shorter arms slwsyscoincide with the axes of the solenoid cores. Thus as the beam; are rocked about the horizontal axis, esch core l9 and each plunger 14 will always move in a vertical direction. if the beams are each set at the proper angles, and if the corresponding chains or csbles on the booms are of the pro er lengths, all circuits will be closed simu tsn'eously. l have shown. st 25, counterweights on each plunger 14 in order that the switch may be quick sct ing. A lug 26 on each Walking-beam is adopted to engage s stationery lug 27 on the casing to limit the downward movement of the niovsl'ile switch member. By melting the lever arm connected. to the ,lunger longer than the lever arm connects to the core I am able to obtain a considerable rnovement' of the switch contact from :1 comparetively smell movement of the core and the ratio of movements may be varied to any extent by changing the relative lengths of the lever arms. it will be seen that the plungers Moorrying the bridging contacts will move simul-' teneously in parallel lines, and therefore all the circuits Will be closed or opened simul; ly. The mechanism by which I socomplisthis result is exceedingly simple and composed of very few ports, and therelt will thus be seen that v move at a, uniform speed throughout thestroke 11 the solenoid core moves at uniform speed.

It will also be seen that each of my unitpole switches is absolutely self-contained and can be operated independently of the other unit-pole switches. 1 can unite any number of these independent switches into a multipole switch by simply cormeoting the short shafts 22 so that all the switches will be operated simultaneously. The number of unit-pole switches so employed can be changed at will for use in transmission systerns, having any desired number of phases.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is- 1.111 an electrically operate switch, a horizontal support, a pair of stationery contact members secured to the lower side thereof, a movable bridging cont-sot member, a vertically movable plunger secured to seid bridgingcontsct member, means for raising he plun er and bridging contact rnember'snd for noldiug the letter in firm engs enient with the stationary contact -mom ers comprising a solenoid supported on said horizontal support, a horizontal shaft mounted in bearings on said support, a lever carried by said shaft, flexible uheens connecting one end of said lever to said plunger, and flexible means connecting the other end of said lover to the core of the solenoid.
